The present invention relates to an attachment for coal conveyer troughs andhas for its prime object to provide means for preventing the buckling of said troughs when in use. 7

Another very important object of the invention resides in the provision of an attachment of this nature which is simple in its construction, inexpensive to manufacture,

thoroughly eificient and reliable in use and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: 7

Figure 1 is a fragmentary bottom plan view of a coal conveyer trough showing my attachment thereon.

Figure 2 is a vertical transverse section therethrough taken substantially on the line 2-2 of Figure 1.

Figure 3 is a top plan view of the plate.

Figure 4 is a side elevation thereof.

Figure 5 is an end elevation thereof, and

Figure 6 is another end elevation thereof taken opposite to that shown in Figure 5.

Referring to the drawings by reference numerals it will be seen that the letter T designates generally a conveyor or trough of conventional construction, the same including a plurality of sections 1 detachably secured together. Each trough section includes a bottom B having sides F provided with ledges L. This type of trough is merely one of the many with which the present invention may be employed. 7

The coupling means for the sections shown in the drawings are of conventional form comprising bolts and nuts 2, 3 engaging eyes or sleeves 8 on bands 7 that extend across the bottoms of the sections and have ends 9 rivetedor otherwise secured asat 10 to angle bars5 riveted or otherwise secured as at 6 to the ledges L as shown in Figure 2.

As is also well known,the trough sections are provided with supporting means comprisingtracks 22 secured at their ends as at 21 to cross bars 19 riveted or otherwise secured to the trough sections as at 20. As is well known thetracks cooperate with rollers (not shown) working in other tracks (11 11 shown). g 1

The present invention comprehends the provision of means for disposition at the joint between adjacent trough sections for reinforcing the joint and to prevent buckling of the conveyor at said joint. In the present instance such means comprises a plate 11 of the shapesuggested in place in Figure 3 and this plate is adapted tolbe disposed at the under side of the sections 1 to bridge the joint between the adjacent ends of the sections. The plate 11 is secured in position through the medium of bolt and nut means .15 engaged with the plate 11 and with the cross bars or straps 7.- At opposite sideedges there- 7.0

of the plate 11 is extended in a manner to provide channels or seats 12 for the reception of the eyes or sleeves 8 on the ends of the straps 7, the outer sides of the channels 12 being substantiallyperpendicular as at 14.

Each seat or channel member 12 at the ends thereof is provided withirings 16 to engage and alined with the sleeves 8 in a manner to accommodate the bolts 2 as shown in Fig ure 1; V

The plate 11 is also provided with oppositely, tapered end portions and one of said end portions is thickened as at 18 so asto positively engage the bottom of one of the sections 1 in the manner suggested in Figure 85 1. By providing the thickened portion 18 provision is made to compensate for the space which would otherwise exist between said one end ofthe plate and one trough section 1 dueto the straps/7, The thickened portion 60 18 also provides means to increase the strength of the joint between the sections and to prevent shearing of the bolt connecting the trough sections.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. This attachment functions as an anti-buckling device to maintain the sections in proper alinement for the free passage of the coal therethrough.

The present embodiment of the invention has been described in considerable detail merely for the purposes .of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. An anti-buckling attachment for a conveyer having trough sections formed with sleeves on the sides thereof at adjacent ends, and bolt and nut means engaging alined sleeves to secure the said ends jointed together; said anti-buckling device comprising a plate adapted to bridge the joint between the ends of the sections and provided at its side edges with channels receiving said sleeves, and rings fixed at the ends of the channels alining with the sleeves and accommodating the bolts.

2. An anti-buckling attachment for a conveyer having trough sections provided with straps at adjacent ends formed with sleeves to receive bolt and nut means for joining said ends of the sections, comprising a plate adapted to bisect the oint between said ends of the sections and provided at its side edges with channels to receive said sleeves, fastening elements securing said plate to said straps; and said plate having one end portion thereof offset into engagement with the bottom of one of said trough sections.

3. A joint for conveyer troughs comprising registering sleeves provided on the sides of the troughs adjacent the ends, an antibuckling plate bisecting the joint between said ends and secured to the troughs, and also having at the sides of the troughs channels receiving the registering sleeves, rings fixed at the ends of the channels and engaging the free ends of the sleeves, bolts fitted in the registering sleeves and extending through the rings, and nuts engaged with the bolts.

4:. A joint for conveyer troughs comprising transverse straps secured to the bottoms of the troughs adjacent the ends, and pro- JOHN VALKO.
